Skin server online, then offline?

The Minecraft skin server is online for about a minute, and then goes offline the next for about an hour. This can be seen in my sig. Anybody know the problem, or is a fix being sent out by Mojang? Does Mojang even know about this?

The signature can occasionally be a little delayed, although it doesn't seem to be the case with this. I presume they know, considering that half of the Minecraft community have laughed at them for it in the past.

It has been offline for the majority of today, though. I'm guessing they know.
